Ok, I'm 1/2 way through the process. I drained the system, pulled and installed the FOMOTO valve on the drivers side block, reverse flushed the radiator, pulled the thermostat and reverse flushed the heater core. I put everything back together and ran the truck up to temp while I cleaned up for the night. I will flush the water tomorrow and then start with the Restore and restore + flushes. I still have a few more questions.
Do you typically reverse flush the oil cooler? If so, how do you get that cover off? I have the Torx30 socket but I'm not sure how I could actually get a ratchet on it. Anybody have a list of the tools or do I need any special tools for it? Do I really need to do this reverse flush?
I pulled the thermostat and it was a massive pain in the a$$. One of the bolts is blocked by a fuel line and I didn't want to remove it. All I could get on it was a small 10mm hand wrench. Are there any special tools that can get to this bolt? Or is it ok to take off the fuel line? If so, what is the size of that fitting? Bigger than a 19mm I already discovered
How the heck do you get that starter out to get that passenger side drain plug out? I was feeling around and couldn't find the top bolt? There are 3 right? Is it really worth pulling that plug or can I just do several more flushes instead?
While the truck was running there was a small drip coming from the lower radiator hose. I traced it up the hose and it appeared to be coming from or very near the bottom of the thermostat. I'm guessing I did't get it tight enough or the hose clamp at the thermostat isn't tight. It was a pain to get back on there.
As always, I appreciate your advice and helpful hints.
